structured mesh

Hi!
I have a question maybe stupid :blush: but at which I can not find answer. I have tried to repeat the mesh reported in the user manual (structured mesh pp 35-36) but, instead of two triangle elements per quadratic elements,

I have four triangle elements.

At this moment, I need a structured mesh with two triangle elements per quadratic elements: how I can obtain this?

I have already tried to reset mesh data and restore the default parameters in the preferences menu.

thanks

ops I have found the problem: some one have changed the preference file and the option Utilities->Preferences->Meshing->Main->Structured Mesher->Symmetrical structured->triangles option was set. I’m sorry.. this is what happen when much people use the same user account :imp:
